delayed job and monit

Question

Can't seem to get delayed job to get running with monit. here is my delayed_job.monitrc file..

check process delayed_job with pidfile /var/www/app/shared/pids/delayed_job.pid
  start program = "cd /var/www/myapp/current && script/delayed_job start RAILS_ENV=production"
                as uid deploy and gid www-data
  stop program =  "cd /var/www/myapp/current && script/delayed_job stop RAILS_ENV=production"
           as uid deploy and gid www-data
  if mem usage > 20% for 5 cycles then alert
  if mem usage > 30% for 5 cycles then restart

I have tried doing a straight command as well and this won't even work without monit. I have to be in the current directory for the script/delayed_job start to function, or it throws an error like..

/var/www/myapp/current/script/delayed_job start RAILS_ENV=production

Monit status just says execution failed.

Answer 1

I guess that that log directory should be in /var/www/myapp/current/ and DJ is trying to mkdir before writing to it. And most probably, the user 'deploy' do not have the permission to write to /var/www/myapp/current.

Answer 2

The issue was I had the followoing in the DJ initializer, to have DJ log to regular rails logs..which doesn't happen btw. It got resolved once I commented it.

Delayed::Worker.logger = ActiveSupport::BufferedLogger.new("log/ {Rails.env}_delayed_jobs.log##", Rails.logger.level) Delayed::Worker.logger.auto_flushing = 1
